    Cluster Validation Analysis on Attribute Relative of Soft Set Theory
    (Springer Link, 2016) Rabiei Mamat; Ahmad Shukri Mohd Noor; Tutut Herawan
    Data clustering on categorical data pose a difficult challenge since there are no-inherent distance measures between data values. One of the approaches that can be used is by introducing a series of clustering attributes in the categorical data. By this approach, Maximum Total Attribute Relative (MTAR) technique that is based on the attribute relative of soft-set theory has been proposed and proved has better execution time as compared to other equivalent techniques that used the same approach. In this paper, the cluster validity analysis on the technique is explained and discussed. In this analysis, the validity of the clusters produced by MTAR technique is evaluated by the entropy measure using two standards dataset: Soybean (Small) and Zoo from University California at Irvine (UCI) repository. Results show that the clusters produce by MTAR technique have better entropy and improved the clusters validity up to 33%.

    Maximum total attribute relative of soft set theory for efficeint catagorical data clustering
    (Terengganu: Universiti Malaysia Terengganu, 2014-03) Rabiei Mamat
    Clustering a set of categorical data into a homogenous class is a fundamental operation in data mining. A number of clustering algorithms have been proposed and have made an important contribution to the issues of clustering especially related to the categorical data. Unfortunately, most of the clustering techniques are not designed to address the issues of uncertainties inherent in the categorical data.

    A replica distribution technique for cluster server system
    (Fakulti Sains dan Teknologi, 2004-01) Rabiei Mamat
    In recent years, the rapid growth in the net traffics and on-line processing load has been significant, particularly in the area of database servers. Many factors are responsible for this growth, such as increasing demand to make information more available or accessible as well as increased information storage both in terms of size and volume. One solution is to resort to a cluster-based server. This however could indirectly increase the use of online applications and thus the demand for non-stop cluster servers. Hence, in designing a clustcr server, the main focus should be on providing highly reliable and good quality service servers. This is important since both hardware and software are failureconstraint. Thus, in preparing a reliable service, the cluster server must be able to maintain its reliability on some data replicas in addition to ensuring that all replicas have one permanent copy of the replica. This thesis proposed a replication technique known as "Neighbor Replica Distributed Technique", which is introduced to achieve a highly reliable service for a cluster server under four-node system.

    Teknik korum dalam sistem pangkalan data teragih
    (Terengganu: Kolej Universiti Terengganu (UPMT), 2000-04) Rabiei Mamat
    Kos komunikasi dan kebolehcapaian data adalah faktor utama ketika menilai perlaksanaan pangkalan data teragih. Keberkesanan faktor ini pula bergantung kepada teknik yang digunakan oleh sistem pengurusan pangkala data teragih. Tiga Teknik iaitu "read-one, write-all (ROWA) , Voting, dan Tree Quorum akan diperbincangkan.
